Abstract: A clutch which reacts to torque overload has a ribbed disc which is produced by plastics injection moulding and which is, along its inner or outer periphery, encapsulated in encircling fashion and on both axial side surfaces by an encompassing ring. Said encompassing ring, owing to shrinkage as a result of cooling, enters into static friction engagement with the ribbed disc, and furthermore engages, by means of bevelled flanks, with ribs running radially on at least one of the side surfaces of the ribbed disc.

Abstract: A compact battery-free event detector having a switching element, which can be remagnetized in a bistable manner by a magnet in a sensor coil which then provides an event pulse and supplies a non-volatile memory circuit with a downstream non-volatile display, is designed to detect recurring movements by virtue of the switching element being able to be moved back and forth relative to the magnet between the activation and regeneration fields of its two poles. The manual operation of an inhalation or injection piston in a medicament dispenser can therefore be detected, in particular, and a dose of medicament, for instance, can be monitored thereby. The display is preferably created using e-paper or e-ink technology which, like the memory circuit which is operated only sporadically, obtains its energy needed to change the indication from the event pulse from the sensor coil.

Abstract: In the case of a multifunctional switch (11) with a panel (14), of injection-moulded ceramic for example, coaxially surrounded by a frame (18), the panel (14) and the frame (18) are produced as separate components, which however are connected to one another in a material-bonding and/or form-fitting manner to form one part by means of an annular light guide (20) that particularly radiates axially parallel and is created by material being injected, introduced by flooding or poured into a gap (17) located between them or is adhesively cemented therein.

Abstract: Using integrated multi-component assembly injection molding, a two-part magnetic rotational angle sensor system having high sensing accuracy is very efficiently integrally produced in a tool as a functional unit that can be directly applied, comprising a polymer-bonded permanent magnet as a passive transmitter part in the first section, which can be rotated relative to the material of the active sensor receiver part, which material is sprayed thereon and then shrunk, with the potted receiver. For this purpose, injection molding materials are used that are mutually incompatible for adhesion and lift off from one another over the mutual contact regions due to shrinkage.

Abstract: A particularly cost-effective electric-motor brake actuator which is useable in a highly flexible manner in respect of structural boundary conditions has an integrally formed cup which is equipped with a permanent magnet assembly and can be equipped with a separately manufactured, electromagnetic rotor assembly. In this manner, the equipment outlay is reduced as is the construction costs.

Abstract: A handle with haptically high-quality surfaces has decorative and functional symbols above, in or beneath a disc, with a corona-like emission being brought about by the end region of a light-conducting hollow cylinder along the peripheral region of said disc, continuously or intermittently circumferentially, which hollow cylinder is fed from a lighting distribution board parallel to the disc. At the same time, the hollow cylinder radiates centripetally into the peripheral region in so far as it comprises light-conducting material. Apertures representing symbols in the disc can contain fibre optic conductors, which are likewise connected to the lighting distribution board.

Abstract: An adjustment device for a carrier plate which can be pivoted about two mutually orthogonal axes and is configured to receive a motor vehicle mirror, includes one motor per axis for moving a non-rotatably and non-tiltably guided linear drive, which is in engagement via a socket with a joint ball on the carrier plate, and a funnel-shaped hub provided with a hollow shaft. A hollow spherical segment of the funnel-shaped hub engages, by spring tabs, in a depression in the form of a hollow spherical segment in the carrier plate, and a spherical segment of the carrier plate is axially elastically clamped in a hollow spherical segment of a housing for drive trains of the two linear drives, thereby locking the hollow shaft on the housing.

Abstract: In order to reduce the wall thickness of housing parts produced by means of plastic injection molding and equipped with decorative layers, such as battery covers of mobile devices, it is recommended to change to a starting material that is a fiber composite material equipped on one side with the decorative layer, from which starting material the housing part is formed in a deep drawing process. Even if a thick decorative layer the outer surface of which is highly embossed for haptic reasons is applied, the resulting wall thickness remains far below the wall thickness for a housing part that can be produced by means of injection molding. An even further reduction of the wall thickness is achieved if a fiber composite material is used as the deep drawing starting material for the shaped part, the decorative material being directly foamed or injected onto the surface of the fiber composite material.

Abstract: A housing shell for electrical measuring, controlling and communication devices, in particular the lower housing part of a cellphone, has very great flexural and torsional rigidity in spite of an extremely small wall thickness if it is formed as a part created by a forming operation from the planar blank of a thermoplastically impregnated long-fibered multi-layered mat. Fine-membered functional elements of likewise thermoplastic material are then molded onto the housing shell in an injection mold.

Abstract: In order to ensure that upon destruction of a brittle article, in particular such as a ceramics element in the form of a frame receiving an apparatus, if possible no free fragments at all become detached therefrom, according to the invention the frame itself or a plate that is integrally moulded therewith and extends over the frame opening remote from view behind the apparatus is non-positively or positively connected at discrete points or in continuous segments in different regions to a connecting part injection-moulded from tough-elastic material. In turn, the connecting part can simultaneously be configured for detachably fastening the ceramics element to the apparatus or to an alternative construction part.

Abstract: In spite of the absence of a pullout fuse block, functional elements comprising simple socket-type connectors come into contact with an external cable in a mechanically and electrically reliable manner, when said cable has a rod-type or sword-type mating connector which engages directly in the connector by means of a radially protruding return baffle, in a sealed manner, through the rear of an opening in the wall of a housing. If, during the plug-in action, an injection-molded skin which first at least partially closes the opening is enlarged or perforated, the breaking edge nestling against the envelope surface of the mating connector in the plug-in direction provides another retraction block with additional sealing and vibration damping.

Abstract: Disclosed is an actuator (11) for electromotively actuating the braking mechanism (22) of a parking brake, especially in a motor vehicle. In order to operate said actuator at low noise even at a high motor speed, the motor (12) of said actuator (11) is provided with a speed reducing element comprising a pinion that preferably has only two teeth and permanently engages with the helical teeth (18) of an intermediate gear (19) as a result of the ribbed shape of the teeth of the pinion, which wind around the pinion shaft (16). The intermediate gear (19), along with a spur toothed pinion (20), directly drives an output gear (21) encompassing the output shaft (14) of the actuator.

Abstract: An easy-to-assemble motor-adjustable throttle valve for fluid channels, especially in motor vehicle air conditioning systems, which can be obtained when a geared motor is integrated in the setting stem without causing an unacceptable reduction of the remaining clear channel cross-section. A built-in housing fitted with a high-speed small servomotor and provided with a strongly reducing shaft gear disposed inn the axial extension of the housing is radially inserted through a side wall of the channel and coaxially inserted into a pot-shaped tapered section of one end of the setting stem, the output wheel of the shaft gear being formed on the inner covering surface of such section.

Abstract: A light assembly includes a housing which defines a longitudinal axis. A hollow holding ring and a reflector are fixed within the housing and spaced apart along the axis. A hollow positioning sleeve is disposed at a rear end of the reflector and is arranged on the axis at a distance forwardly from the holding ring. A tube extends along the axis and includes front and rear portions. The front portion is mounted in the positioning sleeve and includes a bulb receptacle for positioning a bulb within the reflector. The rear portion includes an electrical connection portion disposed in the holding ring. The tube is inserted axially through the holding ring and the positioning sleeve and into the reflector and then is rotated about the axis in order to cause the tube to become locked against axial movement relative to the reflector, as well as to bring an electrical contact into connection with an electrical power supply.

Abstract: In order to electrically reverse the motorized pivoting actuator 11, used for example to adjust an exterior mirror with restricted angles of movement and to return the mirror into a working position after it has been pivoted by external means (either by hand, or as a result of a collision), engagement of the coupling actuator 16 is axially detached, as a result of an external pivoting of the coupling output drive 18, against an elastic restoring force and the coupling output drive is pivoted in relation to the coupling actuator, according to the effective torque. Thus, the coupling output drive is also brought out of its restricted trajectory, in such a way that the drive motor 13 can rotate the coupling actuator 16 freely, until the coupling actuator and the coupling output drive 18 reach a relative position, which has been predetermined in the construction concept in said position, and the coupling claws 28 re-engage in the recesses of the opposing pinion 16 or 18.
